复杂事件处理发动机与专家系统发动机之间的主要区别是什么?
我何时应当使用一种或另一种方法?
如果时间对你的决定模式有重大影响,CEP发动机将提供帮助。 例如:如果Y和Z事件在同一时间窗口发生,决定发射X。 另一个例子是,在时间窗口上合并事件的能力。
时间的另一个影响是相对制约: 因此,你希望在短时间内(例如100米或更少)处理事件。 在这种局势中,临时选举委员会非常合适。
但是,这两种技术是相辅相成的。 具体来说,一些CEP工具有推论规则。 或者,你可以有一个初步处理阶段,有CEP发动机(过滤、汇总、事件组成),然后请一个专家系统来决定与您的合并复杂事件做些什么。
这里有一条关于CEP的某些使用案例的条款,可帮助:。
They are different. @MDE wrote about SEP, but expert system gives decisions. It do not process events, its task to give answer based on (X, Y, Z, ....) parameters. If you want to trigger events then it is CEP, but if you need analyzes of them, so it s expert system. As @Bob wrote, thay can be used together: CEP to capture event Expert System to "think of it" And then, SEP to fire it back, for example.
